Everywhere under 3500 except idle. I only have one ground currently and was going to put another on the other side of the engine.
Yeah car ran normal before the build, but it also did about 200 miles on the build before it started acting up, all without the map plugged in
For the additional ground on the pressure sensor, do mean just splice it inline with the ground wire and run it to chassis , or is their a common chassis ground that can be relocated closer?
